Tool is a progressive metal band formed in 1990, by Maynard James Keenan (vocals), Adam Jones (guitar), Paul D'Amour (bass), and Danny Carey (drums). The band released their first album "Undertow" in 1993. It charted in the top 100 in the US, Australia, Canada, the Netherlands, and New Zealand. D'Amour left the band in 1995 and was replaced by Justin Chancellor. In 1996, Tool released its sophomore album "Ænima" (1996), which included the band’s first Grammy-winning single, also called "Ænima." "Lateralus" (2001), the band’s third album, was the first of three to consecutively top the US Billboard 200 chart. It was followed by “10,000 Days” (2006) and “Fear Innoculum” (2019), the band’s first album in 13 years. The album’s 10-minute and 21-second title track holds the Guinness World Record for the longest song to chart on the Billboard Hot 100 chart, where it peaked at 93. Keenan is also a founding member of A Perfect Circle and Puscifer.
